Here in Central Oregon there is a huge slacklining population. Just about every sunny day you can run by the park and see a line or two up. So far no one has seemed to care about the fact that absolutely no one uses tree friendlies, but it seems to me that with the popularity of slacklining increasing locally, people will soon begin to notice that the trees are taking some wear.

Well, for those of you who don't know, Metolius climbing supply is located here in Bend, OR, and I happen to be lucky enough to work there. So I approached by boss and proposed that Metolius make a bunch of urethane tree friendlies and pass them out to local slackliners if they promise to use them whenever they set up their lines. My boss in turn proposed the idea to the owner (Doug) and he went for it. So in the next couple weeks I'll be designing and producing a set of 10 tree friendlies to be passed out as a trial run to see how well they work, get used, etc.

In either case--if they're successful or not--I thought that it was awesome that Metolius would be willing to shed a few bucks to support slackliners and protect the sport.

As for right now, tree friendlies won't be offered in the catalog, but who knows...

If anyone feels led, I think it would be a nice gesture for folks to call or e-mail the company (especially Doug, or my boss Karl) and give them a quick thanks, or affirmation of support.

Once I get a few prototypes built I'll post some pictures....if you've got ideas feel free to send them my way too.

trees respirate through the roots i think, and also through the leaves, (stomata if my biology is right). But in the previous posters defense, how would you feel if you had some webbing wrapped around your neck with several hundred lbs of tension permanently?

What I was thinking was making them with some lengths of 1"x1/2" stapled to some carpet (for the outside of the protector), probably about 18" long to spread the load and allow airflow to prevent permant moisture that can lead to mould/fungal disease on the tree. I got this and a nasty mark on a tree from a permanent line in my garden last year...

That's a good point. I once left some cardboard on a tree for several weeks. When I took it off there were about 500 ear wigs that had decided to move in.

It looks like we've pretty much settled on a design, and in doing so we have opted for simplicity for the time being. It needs to be simple because we'll be making them in b/w the normal production schedule, and b/c we'll be giving them out locally for free for the sake of protecting local trees (and slacklining). If we find that there is a cry for them on a larger scale, it may end up in the catalog, but that is all up in the air--and a decision beyond my pay grade ;)

So, for the time being making something with many pieces would be out of the scope of this project. However, like I said, if there is a demand, and a sustainable market, something more elaborate may be likely in the future.

This is a cool idea...it's exciting to see people come up with their own ideas, and make something out of it. I hope this works out for you, and that you get Metolius to put it in their catalog and bump you up to a higher pay bracket

I really don't think that this product solves the tree-stress problem one bit.

You might be right. We're testing a couple different versions through community slackers right now. The version above does help prevent deep wear on the bark of the tree, but it doesn't solve the problem of spreading out the load. But, I think we've got that figured out too. Time will tell.
